The Duke of Cambridge, 31, is thus ending a period of more than seven and a half years of his military career.
In the past three years, the prince has worked as a helicopter pilot in the rescue missions undertaken by the Royal Air Force military.
Prince William – who attended 156 rescue operations, helping to rescue 149 people – carried out his last mission as a pilot on Tuesday.
A statement to People reads:
“He will continue to support the work of The Queen and the Royal Family through a program of official engagements, both at home and overseas, with The Duchess of Cambridge.”
“The Duke will work closely over the next twelve months with the Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry. He will expand his work in the field of conservation, particularly in respect of endangered species. The Duke will continue to work with his charities on issues relating to children and young people, veterans and serving members of the Armed Forces.”
Also, the Duke of Cambridge is “currently considering a number of options for public service.”
